Safety sensors and switches
Universal-use standard M12 cables save time and money during installation and assembly. They also help avoid wiring errors, gain clarity and ensure reliable monitoring.
Balluff Magnetic/REED safety switches ensure wear-free access protection at guard doors. When used with a spacing element, you can even install these magnetically coded safety switches in a ferromagnetic environment. And transponder-coded RFID safety sensors are the answer if greater vibration resistance and tamper resistance in guard door monitoring are required.
Direct monitoring of robot work areas and end-of-travel of metallic tool holders in industrial environments can be accomplished electronically. This is simple to do using Balluff's non-contact, inductive safety sensors because unlike traditional safety switches or RFID safety sensors no special mating component is required, and these sensors are vibration resistant.
As is the case with all Balluff safety switches and sensors, the inductive safety sensors can be directly connected to the Safety over I/O module, which bundles all signals and forwards them via an IO-Link master module to the safety controller. As a bonus, you benefit from all the advantages of an intelligent Industry 4.0 solution.
Safety switches with a separate actuator are interlock devices which simultaneously provide personnel and machine protection. When used with a machine controller and an isolating protection device, they secure the hazardous area against access.
Inductive safety sensors detect end-of-travel and positions of metallic objects without contact. Unlike traditional safety switches or RFID safety sensors, they require no special mating part, only standard M12 plugs. OSSD outputs can be used to easily connect the safe sensors to any desired safety processor.
Non-contact, magnetically-coded REED safety switches are outstanding for monitoring guard doors – especially in environments where contamination or dust is expected. The non-contact operating principle makes them insensitive to mechanical play, for example when doors settle or are imprecisely aligned. This makes the safety switches easy to install. With separate processing electronics, the safety switch can be used for applications up to PLe/SIL 3.
Magnetic safety encoder systems feature a safe incremental sin/cos interface and a safe absolute SSI or BiSS C interface. This makes them ideal for safety applications (certified by TÜV Rheinland). A measuring length up to 48 m and very high repeat accuracy (< 1 µm) makes them are highly versatile.
Non-contact, transponder-coded safety sensors offer tamper resistant, wear-free access security for guard doors and flaps. They are insensitive to contamination, vibration and mechanical play. These devices can be used reliably in applications up to PLe/SIL 3. Their compact size makes them easy to integrate, while an optional integrated magnetic clamp can be used to hold protection devices in position.
